According to the official bestiary (now removed), hobgoblins often chew limpwurt roots, which may be a reference to the common drop of these roots for hobgoblins. In addition, the minitrice pet use them as food, which may be related to limpwurt roots being a common drop of cockatrices.

Three limpwurt roots are found in the chest in Evil Dave's compound in New Varrock. They can also be used to make strength potions, but the potions cost 5 zemomarks instead of coins.

Limpwurt roots used to look identical to arcenia roots, until an update around 2005 gave them their current appearance.

They cannot be stacked using magic notepaper. Upon trying to do so will yield the message "nothing interesting happens". Withdrawing noted forms from the bank will still work and players still also receive noted drops. It is unknown why this is like this.
